Abstract:

This paper reports a study into the dynamics of displacing a railroad turnout's switches with a direct start of electric motor and a controlled DC electric drive in the MATLAB environment. The emphasis of simulation was the investigation of processes taking place in the kinematic links of a railroad turnout in the dynamics of its switch displacement. The estimation was based on the optimization criteria for a switch displacement process: the pulse of the impact of a switch against the frame rail, elasticity force in the working rod and a switch turning time.

Abstract:

THE PURPOSE. In controlled AC drives used on continuous-action mechanisms, which include conveyors, conveyors, cranes, the most widespread are asynchronous motors with a phase rotor, controlled mainly along the rotor circuit using various regulators with low energy efficiency. To improve the energy efficiency of an electric drive based on ADFR, it is proposed to develop a control system that combines the principles of frequency control of the motor along the stator circuit and powering the rotor circuit with constant voltage, which allows the electric drive to be considered synchronized.

Abstract:

Distributed control is investigated to solve an electric vehicle switched optimal control problem faster than centralized control without significant performance change. The powertrain includes a cooling system, supercapacitor, and two switched mode components: a battery with discharging and charging modes and an electric drive with motoring and generating modes. Control-oriented component power flow models are developed with mode and temperature dependence. Component specific power and thermal management optimization problems, subject to these models, require solution for overall powertrain m

Abstract:

Availability and continuous operation under critical conditions are very important in electric machine drive systems. Such systems may suffer from several types of failures that affect the electric machine or the associated voltage source inverter. Therefore, fault diagnosis and fault tolerance are highly required. This paper presents a new robust deep learning-based approach to diagnose multiple open-circuit faults in three-phase, two-level voltage source inverters for induction-motor drive applications. The proposed approach uses fault-diagnosis variables obtained from the sigmoid transforma

Abstract:

The operation features of the stop valve electric drive are analyzed. It is found that the drive of stop valves, implemented on the basis of induction motors, is characterized by low energy efficiency. For the purposeful improvement of the energy efficiency of the electric drive, a method is developed for estimating the energy efficiency of the valve module. The need to develop the method is due to the fact that energy efficiency estimates based on international standards are valid for steady-state operating conditions, provided that the time of transient processes is neglected.

There is growing interest in using electric motors as prime movers in mobile hydraulic systems. This increases the interest in so-called pump-controlled systems, where each actuator has its own drive unit. Such architectures are primarily appealing in applications where energy efficiency is important and electric recuperation is relevant. An issue with pump-controlled systems is, however, mode-switch oscillations which can appear when the pressure levels in the system are close to the switching condition.

Brushless DC motors are often used as traction motors in electric vehicles due to their high power density and efficiency. The dc-link electrolytic capacitor is the most vulnerable part of the brushless DC motor drive system, and it determines the reliability of the motor drive system. Therefore, it is of great importance to monitor the life of the dc-link electrolytic capacitor in the drive system.

The stress of each power device when it is subjected to thermal jumps from a few degrees up to about 80 °C was analyzed, starting from the computation of the average power losses and the commitment of the electric drive. A customizable mission profile was considered where, by accounting the working conditions of the drive, the corresponding average power losses and junction temperatures of the SiC MOSFETs composing the inverter can be computed.

Therefore, this paper proposes an MPC that can effectively improve control performance, where the switch transfer sequence in the switch constraint m
